问题 I am on Windows 10 using pypy3.6-v7.3.0. I am trying to install numpy with pip install numpy , but I keep getting the error: error: Microsoft Visual C++ 14.1 is required. Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft.com/downloads/ . However I already have Visual Studio Community 2019 installed, and my C++ build tools are fully up to date. Edit: Here is the new error I am getting after installing build tools manually: Collecting numpy Using cached https://files

使用pipenv管理你的python项目

怎么使用pipenv管理你的python项目 原文链接： https://robots.thoughtbot.com/how-to-manage-your-python-projects-with-pipenv 　　在thoughtbot，我们用Ruby和Rails工作，但通常我们总是尝试使用最合适的语言或者框架来解决问题。我最近一直在探索机器学习技术，所以Python使用地更多。 　　Ruby项目和Python项目处理之间的一个很大的区别就是管理依赖关系方式的不同。目前在Python语言中没有类似于Bundler或Gemfiles的东西，所以通常Python开发人员将使用Virtualenv创建一个虚拟环境，再创建一个依赖包列表requirements.txt，然后他们可以使用 Pip进行安装。 　　这种方法一般都会工作正常，但有时它会表现出一些怪异行为，因此你必须手动安装或删除某些特定版本的包，并记得定期更新requirements.txt文件，以保持项目环境的一致。特别是当你想要在你的虚拟环境中安装Python包，但它不一定与项目本身相关联。 此外，一些项目有时会保留requirements.txt文件的两个版本——一个用于开发环境，一个用于生产环境，这可能会导致更多的复杂性。 　　幸运的是，Kenneth
